Mac Error Message Generator
A macOS alert is laid out completely differently from a Windows dialog: there is no title bar, the icon sits centred at the top, the headline is bold and centred above smaller body text, and the buttons sit centred at the bottom with the default one filled in blue.
Getting that layout right is the whole point — a Windows dialog recoloured grey does not read as a Mac. This generator uses the real Aqua alert geometry.
Nothing is uploaded. The popup is drawn on your device — it is cosmetic only.
